Abstract
The utility model discloses a kind of radiator structure of round built-in motor controller, this radiator structure comprises the heat sink strip be arranged on inside die casting aluminium shell, and described heat sink strip is segmented heat sink strip.The utility model only needs open form timber die, mould and finished product price all much cheap than compression mod, also not easily can not insert too much in circuit board because of heater element mosfet pin when producing in addition.
Description
Technical field
The utility model relates to a kind of radiator structure, specifically the radiator structure of round built-in motor controller.
Background technology
Controller plays a part core component in electric bicycle car load electric system.And traditional controller is generally as independent functional part, from integrally, have oneself independently radiator structure.When same car load coordinates, except integrally putting into the mode of electric vehicle lithium battery housing, the cooperation occurred with built-in motor had, controller is loaded built-in motor inside, in the mode loading motor internal, maximum trend is that controller joins shell no longer separately, but motor and controller are realized integration, and make full use of the large area heat radiation of motor, for the heat radiation of controller is offered help.Under the prerequisite of this technical development background, how to solve the heat radiation matching problem of motor and controller, along with the realization of different schemes, also having increasing problem needs to solve.
The heat radiation aluminum strip of the built-in round controller of this type of built-in motor is with being with arc surface contact heat radiation between motor housing, due to circular arc aluminum strip causes this aluminum strip must open die casting with the mounting structure between controller heater element mosfet could be shaping, not only cost can increase, simultaneously, due to two faces of will fitting on an arc surface, the laminating out-of-flatness that may form two arc surfaces during mounting screw also may be caused.
Utility model content
Goal of the invention: in order to overcome the deficiencies in the prior art, the utility model provides a kind of radiator structure of segmented, to solve controller heater element mosfet on round with the heat radiation overscale problems between motor housing.
For solving the problems of the technologies described above, the technical solution of the utility model is a kind of radiator structure of round built-in motor controller, comprises the heat sink strip be arranged on inside die casting aluminium shell, and described heat sink strip is segmented heat sink strip.
Described heat sink strip is aluminum strip.
Described heat sink strip is divided into four cuboid heat sink strips by circular heat sink strip.
Described every root heat sink strip is fixed 1-2 controller heating power element Mosfet.
Described every root heat sink strip is all screwed from die casting aluminium outer side face.
Described screw is that M3 countersunk head amasss tooth screw.
Beneficial effect: the utility model only needs open form timber die, mould and finished product price all much cheap than compression mod, also not easily can not insert too much in circuit board because of heater element mosfet pin when producing in addition.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, a kind of radiator structure of round built-in motor controller, comprises the heat sink strip 2 be arranged on inside die casting aluminium shell 1, and described heat sink strip 2 is segmented heat sink strip, and heat sink strip 2 is aluminum strip.
Heat sink strip 2 is divided into four cuboid heat sink strips by circular heat sink strip, every root heat sink strip 2 is fixed 1-2 controller heating power element Mosfet3, and every root heat sink strip 2 is all fixed from die casting aluminium outer side face screw 4, and screw 4 amasss tooth screw for M3 countersunk head.
This kind of mode can increase internal circuit board area on the one hand, saves aluminum strip mould and single aluminum strip cost simultaneously.And in actual production, only need the frock clamp of configure dedicated first to lock in aluminum strip by controller heating power element Mosfet, then the heating power element Mosfet insertion circuit board wave soldering of band aluminum strip is completed.Can enhance productivity to a great extent.
The above is only preferred implementation of the present utility model; be noted that for those skilled in the art; under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
